GL-E750 MUDI convert multicast to rtp gstreamer -- missing plugins

I installed the gstreamer-1.0 packages on the GL-E750 and want to try a pipeline like this where I am converting the mpeg-ts feed to h264rtp without any decoding/transcoding. There appear to be some missing gstreamer modules. Does someone from gl-inet maintain the gstreamer1.16 packages or does it flow from upstream? Is there a way to request inclusion of the missing plugins/modules?

Thanks in advance

gst-launch-1.0 -v udpsrc multicast-group=239.255.14.31 port=11045 !
video/mpegts ! tsdemux ! h264parse ! rtph264pay config-interval=10 pt=96 ! udpsink host=1.2.3.4 port=5600 

The tsdemux and h264parse modules are missing when I do a gst-inspect-1.0

gst-inspect-1.0 | egrep "264|tsdemux"
typefindfunctions: video/x-h264: h264, x264, 264
rtp:  rtph264depay: RTP H264 depayloader
rtp:  rtph264pay: RTP H264 payloader
